<
operating system> ("Linus Unix") /li'nuks/ (but see below)
An implementation of the
Unix kernel originally written
from scratch with no proprietary code.
The kernel runs on
Intel and
Alpha hardware in the general
release, with
SPARC,
PowerPC,
MIPS,
ARM,
Amiga,
Atari, and
SGI in active development. The SPARC, PowerPC,
ARM,
PowerMAC -
OSF, and 68k ports all support
shells,
X and
networking. The Intel and SPARC versions have
reliable
symmetric multiprocessing.
Work on the kernel is coordinated by Linus Torvalds, who holds
the copyright on a large part of it. The rest of the
copyright is held by a large number of other contributors (or
their employers). Regardless of the copyright ownerships, the
kernel as a whole is available under the
GNU {General Public
License}. The GNU project supports
Linux as its kernel until
the research
Hurd kernel is completed.
This kernel would be no use without
application programs.
The GNU project has provided large numbers of quality tools,
and together with other
public domain software it is a rich
Unix environment. A compilation of the
Linux kernel and these
tools is known as a
Linux distribution. Compatibility modules
and/or
emulators exist for dozens of other computing
environments.
The kernel version numbers are significant: the odd numbered
series (e.g. 1.3.xx) is the development (or beta) kernel which
evolves very quickly. Stable (or release) kernels have even
major version numbers (e.g. 1.2.xx).
There is a lot of commercial support for and use of
Linux,
both by hardware companies such as
Digital,
IBM, and
Apple and numerous smaller
network and integration
specialists. There are many commercially supported
distributions which are generally entirely under the GPL. At
least one distribution vendor guarantees
Posix compliance.
Linux is particularly popular for {Internet Service
Providers}, and there are ports to both parallel
supercomputers and
embedded microcontrollers.
Debian is
one popular
open source distribution.
The pronunciation of "
Linux" has been a matter of much debate.
Many, including Torvalds, insist on the short I pronunciation
/li'nuks/ because "Linus" has an /ee/ sound in Swedish
(Linus's family is part of Finland's 6% ethnic-Swedish
minority) and Linus considers English short /i/ to be closer
to /ee/ than English long /i:/ dipthong. This is consistent
with the short I in words like "linen". This doesn't stop
others demanding a long I /li:'nuks/ following the english
pronunciation of "Linus" and "minus". Others say /li'niks/
following
Minix, which Torvalds was working on before
Linux.
